Title: Air compressed radial tyre
Inventor: USHIKUBO TOSHIO
IPC: B60C9/22
Filed: 1986-03-26
Abstract: PURPOSE:To prevent separation at the end part of a belt layer and to improve durability at high speed by arranging the constitution in such a way that the tension rate of a cord in an auxiliary layer provided at the outside of a belt layer may be uniform in the width direction along a belt layer curved face, in an extremely flat tyre. CONSTITUTION:An auxiliary layer cord 61 is wound from one end in a spiral shape in a range to cover a belt layer 50 in a range a little wider than the layer 50 so as to form an auxiliary layer 60 having two layers as a whole, when forming a tyre. Then the winding tension of the code 61 in both side ranges W2 of the auxiliary layer 60 and the winding tension of the cord 61 in a central range W1 are performed properly. For example, they are determined as about 1,140g/piece in W2 and 800g/piece in W1. And they are so formed as to be united with a tread rubber. By this constitution, the tension rate of the cord 61 of the auxiliary layer 60 is made uniform in the width direction along the curved face of the belt layer 50 and the force up of the belt layer end part resulting from the centrifugal force of a tyre is restrained and the separation can be prevented.
